What Is A Reverse Osmosis Filtering System?

Also referred to as an “RO” system, Reverse Osmosis is a method used to purify water by passing it through a semipermeable membrane to remove almost all impurities.

What makes RO systems special, is the fact that it’s able to remove very fine particles either dissolved or suspended in the water, something that other water filtering systems fail to achieve. This means that reverse osmosis filters ultimately offer better water quality.

The Science Behind Reverse Osmosis

If you want to understand how reverse osmosis filter systems work, you’ll first need to understand the main concepts of osmosis.

Osmosis is a naturally occurring process where the concentration of particles in water is brought to equal values by utilizing a semipermeable protein membrane. When water passes through the membrane, the concentration of dissolved particles on either side of the membrane becomes equal.

To make things simpler, let’s say you have two containers: one has fresh water, and the other has a saline solution. If both containers are connected through a pipe but separated by a semipermeable membrane, the freshwater will migrate towards the saline container.

This happens because the semipermeable membrane allows water molecules to pass through as solutions have a natural tendency of traveling from areas of low concentration to areas of high concentration until an equilibrium state is reached.

The semipermeable membrane permits only small particles such as water molecules to bypass its barrier, however, it prevents larger molecules including minerals, salts, and bacteria from flowing through.

Reverse osmosis basically follows the same idea, except in reverse. Instead of allowing the shift of low concentrated solution towards the higher concentrated one, external pressure is applied to the concentrated solution, forcing it through the membrane to the lesser concentrated one.

The membrane blocks out molecules of bigger size, so you get clean water out of the other side, free from microorganisms, salts as well as most contaminants.

What Are The Stages of Reverse Osmosis Systems?

Typically, a reverse osmosis system will consist of at least 5 filtration steps, some even go as many as 10 stages of additional purification which are optional. As water travels through each level, a different kind of treatment is applied before it advances on to the next step to finally come out of the faucet ready for consumption.

Regardless of how many steps an RO system offers, there are 5 stages you’ll usually find repeated in all brands. Sure, they might have different names, but they all do the same thing. Here’s a brief explanation of the major purifying steps:

1. Sediment Filter

This is the first pretreatment step water goes through. It’s where larger particles like clay, stones, rust, calcium carbonate, and silt are removed from the water. Such sediments will negatively affect the taste and appearance of your water.

By removing these contaminants, the sediment filter also serves to protect the following filters from being damaged. Most manufacturers use a 5-micron filter for this stage, so any particles larger than 5 microns will remain blocked out.

Note that the sediment filter requires the most frequent replacement because it’s the initial filter to come in contact with the water, regular changing should be done every 6 months or so.

2. Carbon Filter

The water then passes through a carbon filter. It’s used to remove harmful chemicals from water such as chlorine, oils, and organic substances which change the taste of water and cause the degradation of the thin membrane of the reverse osmosis filter.

The oils can easily plug the reverse osmosis membrane while chlorine eats away the pores on the membrane, resulting in a higher flow rate which allows more contaminants to pass into the stream. The carbon filter should be replaced once a year with regular use.

3. Reverse Osmosis Membrane

The most crucial part of the filtration system is, of course, the reverse osmosis membrane. This is where water has to pass through the membrane, which blocks out the majority of contaminants.

The RO membrane is capable of removing the smallest particles according to their weight, size, and ionic charge. Any molecule larger than 0.0001 microns or has a molecular weight of more than 200 is filtered out of the water. This includes inorganic compounds such as fluoride, lead, arsenic, and copper, as well as radioactive components.

RO membrane also significantly reduces impurities called Total Dissolved Solids (TDS) which refers to inorganic salts such as sodium, calcium, and magnesium.

4. Remineralizing Filter

After water travels through the reverse osmosis filter, it becomes highly pure yet slightly acidic and lacking some healthy minerals. A remineralizing filter reintroduces these minerals, mostly calcium and magnesium, which also helps restore the PH balance and improves the taste.

5. Storage tank

Here, water is stored after it bypasses the major filtration steps. Reaching this point in most systems, water is ready to be used out of the tap.

6. Optional UV Filter

Adding a UV filter is a great way to remove biological contaminants as it destroys microorganisms such as bacteria, viruses, and fungi. UV rays penetrate pathogens causing their destruction.

7. Optional Color Changing Resin Deionization Filter

After passing through the reverse osmosis filter, water usually carries residual amounts of Total Dissolved Solids (TDS). The Color Changing Resin Deionization filter removes the remaining TDS.

8. Final Carbon Filter

This one is considered a polishing filter because it removes any unpleasant tastes and odors that may be lurking in your water or have been picked up from the storage tank.

What to Consider When You’re Buying A Reverse Osmosis Filter System

It’s no secret that reverse osmosis systems offer excellent water purification, however, they also come with hefty prices. Since it’s safe to say that you don’t want to waste your hard-earned money on a random filter that lets you down two months in, here are some points to look at before making a purchase:

Source of Water

Generally, there are two types of water sources; well water and city water.

In the countryside or suburban areas, water usually comes from private wells which means that it’s not pretreated before it reaches your house. Such water has high levels of contamination from harmful chemicals to toxic microorganisms, so you’ll be needing a reverse osmosis system with a UV filter.

On the other hand, water in urban regions reaches you after it gets purified in a water treatment plant, consequently, it’ll contain less contamination. For homes in cities, an entry-level of reverse osmosis filters should be enough for safe water consumption.

Water Pressure

You need adequate water pressure to push the feed water through the membrane and filter out the pollutants. Most urban households provide the minimum water pressure requirement of 40 PSI (pounds per square inch). However, if your source water lacks such pressure, you’ll need an RO system with a booster pump.

Water Flow Rate

The water flow rate of your system determines how much water you’ll be getting. This flow rate depends on various factors such as water pressure and temperature.

You should be aware that the actual production rate (GPD – gallons per day) maybe 60% to 80% of the declared system GPD rating as the optimum conditions for similar outputs are difficult to mimic.

For common households, a 59 GPD-rated system should be enough, but a family of 8 members or more will need an RO system with at least a 90-100 GPD rating.

Budget

What you need to consider here, are the two types of cost: the initial cost as well as the maintenance cost.

The initial cost begins and ends with the purchase of the reverse osmosis filter system itself, while the maintenance cost involves how much you’ll pay for replacing filters and faulty parts. Therefore, the more you need to change the filters, the more money you’re going to spend.

Wrap Up

To me, reliability is important when it comes to making large purchases. If I’m going to spend my money on a reverse osmosis filter system, I need to make absolutely sure I’ll be getting pure water for many years to come. This is why my vote goes to the Home Master TMHP HydroPerfect Reverse Osmosis Water Filter System. Not only is it highly dependable, but it’s also backed up by 5 years of warranty.

However, the price point can be a bit too much for those on a budget, in which case, I’d strongly recommend the iSpring RCC7 5-Stage Reverse Osmosis System, as it offers great filtration at a decent cost.
